2. Low-noise block downconverter - Wikipedia

   en.wikipedia.org/wiki/Low-noise_block_downconverter

   Instead of block-downconverting the whole received spectrum, an SCR LNB downconverts a small section of the received signal (equivalent to the bandwidth of a single transponder on the satellite) selected according to a DiSEqC-compliant command from the receiver, to output at a fixed frequency in the IF. Up to 32 tuners can be allocated a ...

3. Fibre satellite distribution - Wikipedia

   en.wikipedia.org/wiki/Fibre_satellite_distribution

   In an optical fibre system at the LNB the four sub-bands are "stacked" in frequency, one above the other, at 0.95 GHz-3.0 GHz (the whole frequency range received in vertical polarisation) and 3.4 GHz-5.45 GHz (horizontal polarisation) and transmitted together as a modulated optical signal down the fibre cable using a 1310 nm semiconductor laser.

4. Multiswitch - Wikipedia

   en.wikipedia.org/wiki/Multiswitch

   Multiple LNB's in the same package, for use with a pair of satellites in known positions just a few degrees apart, received on a single fixed dish. The individual LNB's in the package may be standard (DC voltage selects polarisation) or stacked (both polarisations output at once, on different frequency).

5. Monoblock LNB - Wikipedia

   en.wikipedia.org/wiki/Monoblock_LNB

   Two monoblock LNB can be connected to one receiving dish using Multi-satellite techniques. However, the expected results of such connections may vary or be sub-optimal. The results may yield low-level signals from some or all of the satellites or it may work well in certain geographically favorable locations.

6. Single-cable distribution - Wikipedia

   en.wikipedia.org/wiki/Single-cable_distribution

   Special LNBs have been developed for use in single-cable distribution systems. All four sub-bands of the Ku band (low frequency/horizontal polarity, high frequency/horizontal polarity, low frequency/vertical polarity, high frequency/vertical polarity) are received by a conventional front end, amplified and downconverted to the L-band, to be fed to a number of SatCR (Satellite Channel Router ...

7. Duo LNB - Wikipedia

   en.wikipedia.org/wiki/Duo_LNB

   A twin-output Duo LNB fitted to a 60 cm dish with only one output connected. (Note that this LNB is mounted using the 19.2°E feedhorn, not in accordance with SES' installation guidelines) A Duo LNB is a double low-noise block downconverter (LNB) developed by SES for the simultaneous reception of satellite television signals from both the Astra ...

8. T10 (satellite) - Wikipedia

   en.wikipedia.org/wiki/T10_(satellite)

   DirecTV supplies BBCs with all 5-LNB K u /K a-band dish systems. The satellite signal from T10 is downconverted at the dish to the frequency range of 250-750 MHz, called "K a-lo". At the receiver when necessary, the BBC in response to a control signal from the receiver blocks any original "K a-hi" signals between 1650-2150 MHz. Then up-converts ...

9. Block upconverter - Wikipedia

   en.wikipedia.org/wiki/Block_upconverter

   An example of a system utilizing both a BUC and an LNB is a VSAT system, used for bidirectional Internet access via satellite. The block upconverter is a block shaped device assembled with the LNB in association with an OMT, orthogonal mode transducer to the feed-horn that faces the reflector parabolic dish. This is opposed to other types of ...
